Micro-pollutants especially estrogens, progesterone, androgens, glucocorticoids, and
growth hormones, are biological and chemical impurities that find their way into natural …

Steroid hormones are involved in the regulation of a variety of processes like embryonic
development, sex differentiation, metabolism, immune responses, circadian rhythms, stress …

Synthetic progestins (PGs) are a large family of hormones used in continuously growing
amounts in human and animal contraception and medicinal therapies. Because wastewater …

The effect of a synthetic progestin, levonorgestrel (LNG), on the sex of exposed embryos
was examined in medaka fish (Oryzias latipes). The aims of this study are to clarify the dual …

Background Recent literatures indicate that maternal hormone exposure is a risk factor for
autism spectrum disorder (ASD). We hypothesize that prenatal progestin exposure may …

Synthetic progestins have become widespread environmental contaminants and may cause
adverse effects on fish. In the present study, we investigated the effects of levonorgestrel …

We have previously reported that prenatal progestin exposure induces autism-like behavior
in offspring through ERβ (estrogen receptor β) suppression in the brain, indicating that …

Synthetic progesterones and estrogens are broadly used bioactive pharmaceutical agents
and have been detected in aquatic environments. In the present study, we investigated the …

Progestins are a broad class of progestational agents widely differing in their chemical
structures and pharmacological properties. Despite emerging data suggest that progestins …

Little is known about the molecular effects of progestins on the hypothalamic-pituitary-
adrenal (HPA) and hypothalamic-pituitary-gonadal (HPG) axes in fish prior to sexual …
